3. Bug Fixes
The following fixes have been made to the FC HBA Driver for Linux Kernel 2.6.x between versions 8.01.07
and 8.01.07.15:
l Corrected SRB reference counting issues.
l Cleared potentially stale sense-data during failover retries
l Corrected timer handling during failover processing.
l Prevented premature IOCTL timeout while issuing passthru commands.
l Corrected compilation error/warning when DEBUG macros are enabled.
l Corrected excessive delay during LOAD-RISC-RAM mailbox command.
l Cleaned up PCI region allocation during a failed probe.
l Corrected "Invalid Lun Configuration issues".
l During FLASH update -- further limit other-function-reset to same PCI domain.
l Read an HBA's serial number during init-time.
l Enabled build.sh to pre-load qla2xxx_conf during initrd build.
l Added 'reschedule' directives during lengthy operations.
l Fixed RSCN handling on big-endian systems.
l Enabled Refresh OptionROM boot-code versions during ISP abort.
l Matched configuration-data by WWPN.

4. Known Issues
l When running on RHEL5 with the ql2xextended_error_logging module parameter enabled, the
system log files may include some softlock detected messages, such as "soft lockup on CPU#0!".
This is a side effect of debug messages printed. We are not aware of any operational failures as a
result of these messages.
l Do not change the load order of firmware modules once a configuration is saved. Manually changing
the load order of the firmware modules (qla2400.ko, qla2300.ko, ... etc) in failover mode can cause
a configuration mis-compare which will result in the driver not finding any paths.
6. Additional Information
This driver must be used with API library v3.00-build15Pre8. To maintain consistency with our upstream
offering, the extended_error_logging module parameter has been renamed to
ql2xextended_error_logging.
Please update any scripts and/or configuration files to reflect this change.
